RELALMAGNET,

To all whom 'it may concern:

Be it known that we, JAMES F. lMoELnor and JOHN E. MAooMnR, citizens ofthe United States, residing at Albany, county of Albany, State of'NewYork, have invented certain new and useful Improvements in RelayMagnets, ythe y'following being a full, clear, `and exact disclosure ofthe one form of. our invention'which we at present Xdeenrpreferable. .uy

` For a detailed description of the present' form, of our invention,reference'may be had to the following specification and to theaccompanying drawlng, which illustrates our invention.

l Figure l is a front elevation of our device, Fig. 2 is a top viewthereof, Fig. 3 is a side view thereof and Fig. 4 shows the armature andits supporting piece.

Referring to the drawing,v C C represent two magnet coils'havingtheircores sup* ported on'the bracket B secured-to the wall A of an'inclosing box. The armature D con sists of a stamped piece of sheetiron having at one Aedge a loose slotted connection with an angalarpieceof sheet metal H (see Fig. 4)`wlnch has at one end a slot z cut thereinthrough which rlugs d on the armature plate project and are bent over soas to retain the connection o f the armature with the plate. At itsopposite Iend the plate H has Ian eX- l tension between. which and thearmature is a retracting spring K. On top of the armature plate is asheet of insulation upon which yis a .sheet metal-projection J formed bybending a rectangular piece of metal into a loop aud rivetino` the endsto the insulating sheet.` The piece J passes loosely through the contactplate'l which is designed to bridge the two stationary contacts R and Pand connect them electrically. Both the contacts andcthev bridging pieceare formed of sheet metal and the contactsare screwed to a bar ofinsulation G which also carries the lafore-4 said angular piece H andwhich is mounted ou two projections E and F from the back plate A. Theaforesaid projection J which enters looselyinto an opening in the bridg-Spcccation of Letters Patent. Application led May 13, 1910. Serial No.561,054.

son ofthe loose connection thus established the opposite angular ends'of the piece T can ves tol the diagonal surfaces of the'contactsP. andR. t

The construction above described provides a highly reliable form ofrelay which is eX- tren'xely simple.' and cheap in construction. sinceits parts are principally formed of sheet metal plates produced by thestamping recess. l n j.

What we claim as new and desire to secure by Letters Patentis:

1. The combination with a magnet of a sheet metal armature, a sheetmetal supporting piece for'the yarmatureand having a loose connectiontherewith, a sheet metal loop carried by said'armature, and a contactpieceloosely secured to said .loofx .2. The 'combination' 'with a magneto'f a sheet metal armature provided with lugs, a sheetmetal supportingpiece having a slot to receive said lugs, andvprovided with an armoverhangix'ig saidfarmature, a contact support carriedby said armature,and a contact pieceloosely secured to said support.

3. The combination with a magnet of a sheet metal armature provided withlugs, a

sheet metal supporting piece having a' slotl "metal loop carried by saidarmature, and a ing plate T is secured by a pin O. By rea-' contactpiece loosely "secured to said support.

The c'ombin'ation'witha magnet vof a sheet metal armature, a sheet metalsup orting piece. for the armature and having a loose connectiontherewith, sai being provided with an arm overhanging said armature,contacts carried by said overhanging portion, a contactpiece, and meanscarried by saidv armature porting said contactl piece.

In witness whereof we have hereunto set our hands, before twosubscribing witnesses,

this 3rd day of May, 1910.
